Patent EP-0428859-A2 (EP)
Inventor: WESSELY HERMANN
IPC: H05K7/20
Filed: 1990-10-11
Abstract: The invention relates to an installation system for electrical functional units, especially for data processing, consisting of a plurality of printed-circuit boards fitted with components, so-called flat assemblies which rest on their component side on cold plates through which coolant flows and to which both the operating and the signal voltages are supplied from the exterior via plug and/or terminal connections. By means of the planar arrangement of flat assemblies, which has already become known, in a grid frame and a common cold plate, through which coolant flows and which rests on the side of the flat assemblies fitted with components, considerable increases in the component packing densities per unit volume were able to be achieved. The increasing requirements made on computers, with which it is intended to carry out an ever greater number of computing operations in the minimum space, necessitates an ever greater component packing density per unit volume, as a result of which the problem of heat dissipation and the supply of the lines is becoming increasingly greater. In order to achieve an even better component packing density per unit volume, the invention provides that a plurality of flat assemblies (2) and cold plates (3) be arranged in an alternation sequence in each case one behind the other or one on the other with parallel surfaces, so that a box-shape is formed. The cold plates (3) are provided with coolant channels (14) and with perforations (21) at right angles thereto, in which pressure contacts (9), constructed in a resilient manner, are arranged one below the other for the wiring of the flat assemblies (2). On the surfaces of the two outer flat assemblies which are not fitted with components (1), connector boards (4) with recesses for holding line connectors (5) for signal supply are provided, operating voltages being connected to the other two sides of the box and the coolant supply (7) and the coolant outlet (8) for the cold plates (3) being connected to the third pair of sides. This enables three-dimensional wiring to be achieved within the functional unit.

Abstract: In a raster output scanner, a system for using one original beam and one facet of a rotating polygon to generate two consecutive scan lines. The original beam is first separated into two beams (24, 25) in a beam splitter (21). The resultant beams are polarized ninety degrees apart, and directed to an acousto-optic (A/O) modulator (22). The beams are a sufficient distance apart so that the A/O modulator can modulate each beam with a minimum of crosstalk. The output beams are then brought together to within one scan line separation by a beam recombiner (23), which is a reversed beam splitter. The beams can be brought together to this close proximity without optical interference because the beams are polarized ninety degrees apart.

Abstract: An acoustic-emission sensor comprising a composite synthetic resin-ceramic piezoelectric element (11) which has a plurality of substantially mutually parallel circular-columnar ceramic piezoelectric bodies (10), the circular-columnar ceramic piezoelectric bodies being polarized in a longitudinal direction and being disposed in a synthetic-resin matrix (11). A potential difference develops between the two end-faces of the composite synthetic resin-ceramic piezoelectric element only with respect to a longitudinal oscillation mode from among acoustic-emission waves which are propagated in the longitudinal direction. Consequently, only the longitudinal oscillation mode is detected. Further, since the circular-columnar ceramic piezoelectric bodies do not possess anisotropy in a radial direction, oscillation of the circular-columnar ceramic piezoelectric bodies (10) in the longitudinal direction is dispersed by the synthetic-resin matrix (11). Consequently, a transverse oscillation mode does not occur.
